SPECIFICATION forming part of Letters Patent No. 642,527, dated January 80, 1900.

Application filed $epte1nber 2, 1899. Serial No. 729,306. (No model.)

To ctZZ whom it may concern:

Be it known that I, FRANK RHIND, a citizen of the United States, residing at Bridgeport, Connecticut, have invented a new and useful Improvement in Lamps, of which th following is a specification.

My invention relates chiefly to lamps such as are used on cycles and other vehicles and especially to those adapted to burn acetylene or other gas. It is intended to render such lamps more efficient and convenient.

In the accompanying drawings, Figure I is an elevation of a cycle-lamp embodying my invention. Fig. 11 shows a substituted portion. Fig. III shows a modification.

1 designates a lamp-body provided with screw-threaded portion 11 and locking-collar 12; 2, a connecting-shell threaded at 21 and provided with stuffing-box 22 and bead 23; 3, a gastube having a head 31 and handle 32; 4 4O burner-tips; 5, a guard-shell; 6, a reflector; 7, a wind-guard; 8, Fig. II, alamptop provided with locking-flange 81; 61, a pivot-pin; 71, a sleeve; 72, a set-screw, the last three parts being only found in Fig. III.

In the example of my invention shown in Fig. I the lamp-body 1 may be of any desired form. As shown, it is provided with an upwardly-projecting internally and externally threaded portion 11, into which a burner-tip 4. is secured. Detachably engaging with the exterior thread of the portion 11 is a shell 2, open to pass freely over the burner 4E and having at its upper end a stuffing-box 22. A guard-shell 5 is secured on the shell 2 at its upper end and at its lower end engages with the collar 12. It is preferably rotatable on the shell 2, so as not to interfere with the screwing of the shell 2 on the portion 11. R0- tatably and gas-tightly secured in the stuffing-box 22 is the gas-tube 3, whose head 31 is laterally pierced to receive a second burnertip 40. A reflector 6, shown as conical, is suitably secured to the head 31. To the open outer end of the reflector 6 is secured a windguard 7, shown as a short perforate cylinder.

The operation of the device will be readily understood from an inspection of the drawings. It is clear that the gas generated in the body 1 will pass through the tip 4t,shell 2, gas-tube 3, and tip 4:0,where it may be lighted.

It is also clear that the burner 4 may be removed, if desired. By means of the handle 32 the gas-tube 3 and connected parts may be turned to throw the light in any desired direction. This is found very convenient, either to protect the flame against a side wind or when a tire needs pumping or any slight repairs are necessary.

In practice it is found that a flame surrounded by an open reflector is quite easily blown out by the wind. I therefore secure to the free end-of the reflector the perforate wind-guard 7, which serves to break up the air-currents and protect the flame.

In Fig. II of the drawings I have shown how the well-known closed lantern-top 8 may be substituted for the device shown in Fig. 1,

the flange 81locking with the collar 12 on the.

bodyl by means of a bayonet-joint, as shown, or in any desired manner. This substitution necessitates the consumption of a greater volume of gas to produce agiven efliciency, but is desirable in very rainy or, windy weather.

In Fig. III, I have shown a modified form of perforate wind-guard adapted to afford a greater protection from either wind or rain than that shown in Fig. I. 111 this form the reflector may well be of substantially hemispherical shape and provided with a pivot-pin.

position in front of the reflector 6, as shown,

or behind and surrounding the reflector, as shown in dotted lines. It is clear that the guard may be set at any intermediate position-e. g., so as to cut off a-wind blowing across the path without so much obstructing the light.

It is understood that many mechanical alterations and changes of form may be made without departing from my invention and that parts of my invention may be used separately-c. g., the turning of the upperportion of the lamp to project the light in any direction is advantageous, whether or not the lamp is supplied with a particular form of wind-guard. It is also understood that while it is of the greatest practical advantage that the inner surface of the portion 6 should be polished or otherwise light reflecting, the function of protecting the flame from wind and storm would be subserved by any concavehood surronndingorinclosingtheburner, so that when in the claims I use the Word reflector I intend to include such a hood.

It is found in the practical use of acetylene-lamps upon cycles or other vehicles that it is impossible to maintain an even production of gas. Hence a flame such as would be used in the construction shown in Fig. I may vary greatly in length, at times extending to three or four inches, or even more. For this reason the usual lens or other glass covering the outer end of thereflector is impracticable; but by the integral or unitary rotation of the burner and the open concave reflector which surrounds and protects the flame the rider of a bicycle is enabled to temporarily protect the flame from a sidelong gust Without seriously decreasing the effective lighting of the road. This integral rotation of the burner and the reflector is particularly desirable where the flame is projected axially of the reflector to avoid destruction of the reflecting-surface.

hat I claim is 1. In a lamp an integrally-revoluble horizontally-disposed burner and reflector, substantially as described.

2. In a lamp an integrally-revoluble burner and open concave reflector, substantially as described.

3. In a lamp an integrally-revoluble horizontally-disposed burner and open concave reflector, substantially as described.

4. In a gas-lamp in combination a body, a rotatable gas -conducting tube and a gasburner and a reflector both mounted on said tube and revoluble therewith, substantially as described.

5. In a gas-lamp in combination a body, a gas-conducting tube, a reflector mounted on said tube and a burner axially disposed Within said reflector, said reflector and burner being adapted to revolve with respect to said body, substantially as described.

6. In a lamp a horizontally-disposed gasburner and a reflector having a horizontal axis surrounding said burner and adapted to protect the flame issuing therefrom, said burner and said reflector being adapted to revolve together around a common axis, substantially as described.

7. In a lamp in combination a body, a rotatable gas-conductin g tube, a gas-burner and a reflector surrounding said burner and adapted to protect the flame issuing therefrom, said burner and said reflector being mounted on said tube and revoluble therewith, substantially as described.

8. In a lamp in combination an open reflector and a perforate wind-guard at the free end of said reflector, substantially as described.

9. In a lamp in combination an open reflector and an adjustable wind-guard at the free end of said reflector, substantially as described.

10. In a lampin combination an open reflector, an adjustable perforate wind-guard and means for securing said wind-guard either in or out of operative position, substantially as described.

11. In alamp in combination an open reflector, an adjustable perforate wind-guard and means for securing said Wind-guard in any desired position, substantially as described.

12. A gas-generator-lamp body adapted to have alternativelysecured thereto a plurality of different burner-inclosing portions, substantially as described.

13. A gas-generator-lamp body provided with separate means for securing thereto a plurality of difierent burner-inclosing portions, substantially as described.

14. In combination a gas-generator-lamp body, means for securing a burner to said body, means for attaching to said body a burner-inclosing portion and separate means forsecurin g to said body a gas-conveyin g portion, adapted to support a burner and a reflector, substantially as described.
